U+1E91 "ẑ" Latin Small Letter Z with Circumflex Unicode Character

U+1E91 "ẑ" Latin Small Letter Z with Circumflex is a specialized alphabetic symbol used primarily in the transliteration of certain languages, such as in the romanization of Chinese (like in the Wade-Giles system for the sound "zh") or in Old English orthography. It represents the letter Z modified by a circumflex diacritic, which often indicates a specific pronunciation, such as a palatalized or fricative quality depending on the linguistic tradition. This character is part of the Latin Extended Additional block in Unicode and is typically encountered in academic or linguistic texts rather than in everyday writing.
